Just had a boo-boo and hope this isn't a double post.
This is a difficult question to answer. Out of my first four HI purchases, only 3 were khuks and two of them were made by Raju (?). One (a 16.5" Chiruwa AK) is my most used khuk, although not my favorite. The other is a 20" AK that gets called out for the tough work. Both are nice. Both do their jobs exceptionally well. I would not say that Raju is my favorite kami. You probably won't hear anyone say that Raju is their favorite kami but as far as I'm concerned, he built me a pair of perfect AK's and I have no complaints. I have a Kumar (as in, made by Kumar) Kobra; needless to say, I can't think of anything to say about that either. It speaks for itself. I've given some things away to people made by several kamis that are all as close to perfection as an object needs to be. I had no complaints. Neither did the recipients.
If someone were to corner me on the topic, I'd say that Bura is my favorite kami. All of the non-khuk HI products in my possession (two Napoleons, one Rose, one AK Bowie) are his work. While I can sometimes find fault in the design, I cannot find fault in the execution. Technical perfection, or at least as close to it as possible. I don't own any of his khuks as of yet although at least one is on the way. His non-khuk works, to me, are flawless, and that's the majority of what I own.
If I had to make a second choice, it would definitely be the good Sergeant Karka. All of my Karka purchases have gone to others as gifts. All were excellent. If we're talking strictly about the market for smaller decorative khuks, I believe he's the best.
I think that I've said so before and I'll say it again just in case - the kami who makes what I purchase is not important to me. I know that it will be good. Whether I like the design or not is on me but as far as execution is concerned, I have no worries. There will be an unbeatable warranty on it, there will be an unbeatable family of knowledgeable HIKV addicts to supply advice, and there will be an unbeatable man making it all happen.
I don't care which name is on the khuk. I know it will be good.

, in case that came off too seriously.
